GBX has been very sneaky in hiding ops points around the Battle School, including hiding one behind some sort of puzzle. I’m not sure at how many people are already aware of this, but I certainly wasn’t until @Ashbweh showed me.
In a room just before you head towards the teleporters that begin the first wave of Battle School, you’ll pass a glass screen with three Mikes behind it. In front of these Mikes are three computer panels which you can interact with, as shown below.
Provided that you select the correct panel, it will cause a chest containing an ops point to spawn just to the right of them. Selecting wrong however, will briefly deactivate the panels and you’ll have to wait a couple of minutes before you can try again.
Before, we were just randomly choosing which panel it might be and hoping for the best, but we’d often get it wrong and end up waiting to try again, only to guess incorrect again. 
I thought there must be something somewhere around here that hints what the right panel may be instead of it just being random each time. So, after a little bit of searching, this is what I found:
In the very first room of the Story Op, where the OM hologram appears, you’ll see three more Mikes on the left and right hand sides. Now, if you take a closer look at the Mikes on the left, you’ll notice this:
The Mike on the left will always be doing something different compared to the other two Mikes. He’ll either be upside down, sitting, or banging on the glass of his barrel. It varies each time you run through the Op. In this case, he’s upside down.
Now, going back to the room with the computer panels, notice the positions the Mikes are in. Familiar? This is how you are able to tell which panel is the correct one.
In my case, the Mike from before was upside down, and so is the Mike on the right, which means that the panel on the right was… well… the right one.
So basically, all you have to do is match up the Mikes, and then to the correct computer panel. Easy peasy.
I hope this helps!
